The zocaloDWM socket has 16 pins, which are typically mapped to the corresponding pins of the DWM module. Below is the standard pin configuration:

Note: Pin assignments may vary depending on the specific DWM module. Always refer to the module's datasheet for compatibility.

1. Mounting the Socket:
   • Solder the zocaloDWM socket onto a PCB or insert it into a breadboard.
   • Ensure proper alignment of the pins to avoid misconnection.
2. Inserting the DWM Module:
   • Carefully align the DWM module with the socket.
   • Gently press the module into the socket until it is securely seated.
3. Connecting Power and Communication Lines:
   • Connect the VCC and GND pins to the appropriate power supply.
   • Use the TX and RX pins for UART communication or the SPI pins for SPI communication, depending on your application.
4. Programming and Testing:
   • If using a microcontroller (e.g., Arduino UNO), connect the relevant pins to the microcontroller and upload the necessary code.

• Voltage Compatibility: Ensure the power supply voltage matches the requirements of the DWM module.
• Static Protection: Handle the socket and module with care to avoid damage from electrostatic discharge (ESD).
• Pin Mapping: Double-check the pin mapping of the DWM module to ensure proper connections.
• Secure Mounting: For long-term use, ensure the socket is securely soldered to the PCB to prevent loose connections.

Below is an example of how to connect a DWM module via the zocaloDWM socket to an Arduino UNO for UART communication:

• zocaloDWM Pin 1 (VCC) → Arduino 3.3V
• zocaloDWM Pin 2 (GND) → Arduino GND
• zocaloDWM Pin 3 (TX) → Arduino Pin 10 (RX)
• zocaloDWM Pin 4 (RX) → Arduino Pin 11 (TX)

// Example code for communicating with a DWM module via zocaloDWM socket
#include <SoftwareSerial.h>

// Define RX and TX pins for SoftwareSerial
SoftwareSerial DWMSerial(10, 11); // RX = Pin 10, TX = Pin 11

void setup() {
  Serial.begin(9600); // Start Serial Monitor communication
  DWMSerial.begin(9600); // Start communication with DWM module

  Serial.println("Initializing DWM module...");
  DWMSerial.println("AT"); // Send an AT command to test communication
}

void loop() {
  // Check if data is available from the DWM module
  if (DWMSerial.available()) {
    String data = DWMSerial.readString();
    Serial.println("Received from DWM: " + data);
  }

  // Send data to the DWM module
  if (Serial.available()) {
    String command = Serial.readString();
    DWMSerial.println(command);
  }
}

Note: Adjust the baud rate (9600) as per the DWM module's specifications.

1. DWM Module Not Powering On:

   • Cause: Incorrect power supply voltage.
   • Solution: Verify that the VCC pin is receiving the correct voltage (3.3V or 5V).

2. No Communication with the DWM Module:

   • Cause: Misaligned or loose connections.
   • Solution: Ensure the DWM module is properly seated in the socket and all connections are secure.

3. Data Transmission Errors:

   • Cause: Incorrect baud rate or mismatched communication settings.
   • Solution: Check the DWM module's datasheet for the correct baud rate and update the code accordingly.

4. Overheating Socket:

   • Cause: Excessive current draw or short circuit.
   • Solution: Verify the circuit for shorts and ensure the current does not exceed 500 mA per pin.

• Q: Can the zocaloDWM be used with other types of modules?
  A: The zocaloDWM is specifically designed for DWM modules. Compatibility with other modules depends on pin alignment and electrical specifications.

• Q: Is the socket reusable?
  A: Yes, the zocaloDWM socket is designed for repeated use, making it ideal for prototyping.

• Q: What is the maximum insertion/removal cycle rating?
  A: The socket is rated for up to 1000 insertion/removal cycles under normal operating conditions.
